In a way, this is a followup to a previous project, applying some of its content to a specific topic. And unlike several preceding books, it has a fairly large bibliography, which was one of the things I've been working on over the final weeks.
Elsewhere in the news, my previous book is going through the final stages of production review before it gets released. I'm not sure exactly when that will be, but I'm hoping for this month. It's partly a gear catalog and partly a history of electrical technology, for the benefit of GMs who want to have authentic toys for their campaign year. I'm hoping it sells well, as we're having higher expenses than usual. . . .
